Consider This

Few would consider there was facial confusion during the 1960s between Mike Nichols (left), famous director, producer, actor, and comedian (1931-2014), and the lesser-known William Redfield, an actor in theater, film, radio, and television (1927-1976). The multi-talented actors were from the same era and both died in NYC. The photo comparison may solve any confusion. 

Likewise, few would compare these two actors, who are not brothers. From left to right, introvert Robert Young (1907-98) and extrovert Richard Denning (1914-98). They had a facial resemblance at certain ages, both were 6' tall and died the same year. Denning was in radio and television plus numerous low-budget films. Young was an A-list actor in high-budget films and had huge success on television.
